Male Pelvic Leiomyoma: Organ-Preserving Resection of a Deep Vascular Tumour in the Seminal Vesicle Using the Da Vinci Xi Robotic System

Pelvic leiomyomas are rare in males, with most cases reported as isolated instances.This study presents a case of a 57-year male with a deep vascular leiomyoma located in the Denonvilliers fascia, who experienced urinary frequency and nocturia.Imaging revealed a welldefined pelvic tumour, and pathology confirmed the diagnosis of a vascular leiomyoma of mesenchymal origin.Given the tumour's size, deep location, and proximity to vital structures, robotic-assisted laparoscopic resection using the Da Vinci Xi system was performed.The procedure successfully preserved organ function achieved complete tumour excision with minimal blood loss and resulted in no complications.Postoperative recovery was uneventful, and no recurrence was observed at the 20-month follow-up.This case highlights the advantages of robotic surgery for complex pelvic tumours, expands its application in urological procedures, and underscores the importance of organ-preserving techniques for benign tumours in challenging locations.
